Perissodus multidentatus   - 3 (1) 6 (3) 26 (17)
Perissodus hecqui   - 14 (4) 9 (6) 13 (9)

  1. * The numbers of samplings conducted at each depth range are given in parentheses. In waters deeper than 40 m, gill nets were deployed for about 1 h. In shallow rocky areas less than 20 m in depth, gill nets were set using SCUBA. Sampling was not conducted at depths of 20–39 m. The anoxic region begins at depths around 120–140 m in this region.
